Price to expect if a RV dealer buys my coach

I sold my 2013 Itasca 27N last spring. First I called PPL motorhomes to see what I could expect to get for it. The person I talked to said that if it was in excellant condition they would probably sell it for 45K to 50K. I decided to try and sell it myself. I put it on Craigs List and within an hour I got a phone call from a local RV dealer. He said that if it was in the condition I had advertized it as they would give me 42K for it. We made an appt. for them to have one of their people come look at it. He was here at 10:00 the next morning and spent about 6 hrs going over every thing and taking pictures which he emailed back to one of their appraisers. They agreed it was as advertized and paid 42K for it. They went through ACH and transfered the money to my bank account, the money was in my account before They would let me sign the title over to them. I figured this was the better deal since it would have cost close to 2K for me to deliver it to PPL.
